This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig49E93BE3886E2BDB8412BCED Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Ivan Voras wrote: > The file system on the virstor device was created with softupdates > enables, as shown... Without softupdates, the I/O requests fail, with the usual spewing of kernel messages from g_vfs_done() in the log, but the application (dd) doesn't receive failure codes. In effect, it looks like the requests are ignored - they fail, but dd continues pumping more requests. Something else occurred to me: what if an UFS metadata update (for example, in cg) fails in this way - that it requires an additional chunk of physical data that's not available, is there a chance that the fs will be corrupted? --------------enig49E93BE3886E2BDB8412BCED Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.4 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGDCcyldnAQVacBcgRAm+UAKDOWa8HNMiwiQute5gF7fTRvP74gACfYtnW RqF7eiQJtXQcSG4yKwZSTWU= =VbO6 -----END PGP SIGNATURE----- --------------enig49E93BE3886E2BDB8412BCED--
